Answer:
He said it would bring white settlers more wealth
Explanation:
To persuade (white) people that the Indian Removal Act was a good decision, he told them the white settlers would get wealthier.
He argued that the Indians were still barbarians with practices and customs beyond understanding, even after many failed attempts to do so.
It was then acceptable to remove them from their ancestral lands in order to allow white settlers to occupy that space and generate more revenues and build new towns for the white population, always in expansion.
